"Pinmike" So I fiddled with the switches. that doesnt seem to do anything. I did get more of an idea of what the issue is, I may have to take off the trough to see more. There is a horizontal plunger (excuse me if thats not the right terminology) with a ball sitting on a microswitch right in front of it at the start of a game or a round. The plunger hits the ball which then hits the other balls located just to the right and that knocks a ball into the lane tot be plunged by the player.
It seems like sometimes when this happens the ball that gets plunged by the horizontal plunger doesnt clear that part that holds the ball from falling back onto the micro switch in front of the plunger. That causes the plunger to wack the ball again (probably because it thinks it made its way around and drained down the middle too quick) firing another ball into the lane to be plunged by the player, except there is already a ball in play yada yada.
Hope thats not too long winded. I am not sure what the mechanism is that stopped the ball from falling back onto the microswitch. My only thought is maybe its sticking or maybe the plunger has a coil sleeve thats shot?
I have pressed the test button a couple times. Nothing seems to happen. It just sits on the screen telling me what the flippers do. Tournament mode shows a similar screen then it moves onto the next menu automatically. I'm thinking maybe the board is bad but I dont know enough about Gottleibs (or many pinball machines) to make that decision just yet.
